Product Description
Komatsu Excavator R130 R140-7 K3V63DT-9COS Hydraulic Pump Assy 31N3-10010 31N3-10011 Main Pump

The hydraulic pump is a critical component in excavators, responsible for converting mechanical energy into hydraulic energy. It supplies high-pressure hydraulic oil to various actuators (such as hydraulic cylinders and motors), enabling smooth and efficient operation of the excavator. High-quality hydraulic pumps ensure durability, energy efficiency, and precise control, making them essential for construction, mining, and other heavy-duty applications.

The excavator hydraulic pump acts as the "heart" of the hydraulic system, converting engine mechanical energy into hydraulic power to drive actuators (e.g., cylinders, motors). Its core principle relies on the reciprocating motion of pistons within cylinders, cyclically altering chamber volume to suction and pressurize oil. As a variable-displacement pump, it dynamically adjusts output flow based on load demand, delivering stable high-pressure (35MPa+) power for precise digging force while optimizing energy efficiency.
